i2c: i801: Fix the i2c-mux gpiod_lookup_table not being properly terminated
commit 0b3ea2a06de1f52ea30865e227e109a5fd3b6214 upstream.
gpiod_add_lookup_table() expects the gpiod_lookup_table->table passed to
it to be terminated with a zero-ed out entry.
So we need to allocate one more entry then we will use.
